Google Panda 2.5 Reversed Or Updated

So the Panda 2.5 update was pushed out by Google on September 28th and then on October 4/5th, Google promised tweaks and some site's hit, confirmed being back and recovered fully.

SearchMetrics reports that 10 of the 30 sites they reported being hit, saw a 80-90% of their visibility improve. But they also said that other sites did not see an improvement.

I spoke with one of those sites (can't disclose, I am sorry) and they said they saw a recovery on October 7th. They even proved it to me, that they fully recovered. So it makes it hard for me to believe the SearchMetrics reports, even if the results are positive or negative.
